INDIANAPOLIS -- Already down a running back, the Pittsburgh Steelers offense took another blow as RB Cordarrelle Patterson was ruled out with an ankle injury sustained in the second quarter of Sunday's 27-24 loss to the Indianapolis Colts.
Patterson was injured on the Steelers' best drive of the afternoon as he picked up a first down in the red zone on a 10-yard gain. A play later, though, wide receiver George Pickens fumbled as he was tackled near the goal line and the Steelers turned the ball over.
Patterson picked up four first downs on that drive and left the game averaging 7.2 yards per carry with 43 yards on six attempts. He also had two catches on two targets for 19 yards.
Without Patterson, the Steelers went back to Najee Harris and added practice squad running back Aaron Shampklin to the mix.
Harris, though, was ineffective, finishing with 19 yards on 13 carries. Shampklin finished with just one carry before halftime for a 5-yard gain.
